Questions
There is no single answer, which is why this page lists 12 of them with their limits stated. If you want to avoid signing up entirely, 9 of these work with no account at all.
5 of the 12 sites here process your file inside the browser and never upload it — they are marked "On device". The rest send your input to their server, which is fine for public material and worth thinking twice about for anything personal.
Nothing in this category has shut down so far. When something does, it moves to the Archive with a named successor rather than being deleted, so the answer to "what replaced it" survives.
